The Timing Cover is the aluminum part on the front of the engine that covers the Timing Chain. It also has a timing mark on the cover and houses the crankshaft pulley seal.

Overview
Depending on the country, 1971 or 1973 saw newer timing covers which differ from earlier covers.
Water pump bolts to the timing cover. And the cover bolts to the front of the block, and passes water through two ports (the square hole, and the round hole).
Matched Set
Japan got this change in June 1970. North America: all A-series engines from 1972 including 1973 A12.
Early Set Multiple-mark Crankshaft Pulley Single-mark Timing Cover
Late Set Single-mark Crankshaft Pulley Multiple-mark Timing Cover
Interchange
The same covers are used by A10, A12, A12A, A13, A14 and A15, except for the first type:
- original Datsun 1000 timing cover, for single-row timing chain
- 13035-18000 ASSY-COVER TIMING CHAIN
- to June 1970, with single timing mark (pulley has multiple marks)
- 13035-18001 ASSY-COVER TIMING CHAIN [updated to fit Double timing chain & pressure tensioner
- from June 1970, with multiple timing marks (pulley has single mark)
- 13035-H1000 (or from second source: 13035-H1010) [Fits all A10 blocks]
Interchange is same for same. The last two will interchange if the complete set of pulley & cover is used.
